Vitamine EIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Curly hair has particular characteristics in elasticity and shape that require a special and different care. Curly hair is more fragile than straight hair and therefore requires specific care.
Every day, hair is exposed to a series of external aggressions : brushing, friction, straightening treatments, heat irons, colouring, perms, pollution, UV radiation, etc...
Ethomega, with high content in Omega 3, is an excellent natural active ingredient for promoting faster and healthier hair growth, nourishing the follicles to stimulate their growth and shine.
Ethomega has proven to restore the hair lipids barrier, increase gloss and avoid hair colour fade after UV irradiation, making hair more resistance to breakage and split ends.
Ethomega has high concentrations of delta and gamma-tocopherol, difficult to find in other botanical oils.
Both PUFA and tocopherol content, shield the hair fibres creating a protective film that prevents protein loss caused by UV damage retaining moisture, preventing photo-oxidation, and providing the necessary lipids for the specificities of this type of hair.Note de contenu : - Evaluation of the anti-breakage efficacy : Protocol

Wet-blue (tannage)Peau tannée au chrome (le chrome donne une couleur bleue)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Mould protection of wet-blue continues to be a major cost and concern to tanners. There is a need for more effective fungicides with low human and fish toxicity and minimum environmental impact.
The advantages and disadvantages of currently used fungicides are reviewed. There are problems associated with reduced effectiveness of some fungicides in the presence of sulfide, bisulfite, oxidising agents or grease.
Systems used to overcome these problems are compared. Also, fungicides which can control difficult moulds, such as Cladosporium, are discussed.
Standard methods for testing fungicidal efficacy are compared with tropical chamber methods. Results of both laboratory and industrial trials comparing a range of fungicides show the benefits of some combinations.Note de contenu : - Introduction : Active components in currently used wet-blue fungicides

KératinocytesLes kératinocytes sont des cellules constituant 90 % de la couche superficielle de la peau (épiderme) et des phanères (ongles, cheveux, poils, plumes, écailles). Ils synthétisent la kératine (kératinisation), une protéine fibreuse et insoluble dans l'eau, qui assure à la peau sa propriété d'imperméabilité et de protection extérieure.
L'épiderme est divisé en 4 couches basées sur la morphologie des kératinocytes (de l'intérieur vers l'extérieur) :
1. stratum germinativum (couche basale à la jonction avec le derme)
2. stratum spinosum
3. stratum granulosum
4. stratum lucidum
5. stratum corneum
Les kératinocytes passent progressivement de la couche basale vers les couches supérieures par différenciation cellulaire jusqu'au stratum corneum ou ils forment une couche de cellules mortes nommées squames, par apoptose. Cette couche constitue une barrière de protection et réduit la perte d'eau de l'organisme.
Les kératinocytes sont en perpétuel renouvellement. Ils mettent environ 1 mois pour aller de la couche basale au stratum corneum mais ce processus peut être accéléré en cas d'hyperprolifération de kératinocyte (psoriasis).

Tests d'efficacitéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : As a result of their complex aetiology and periodicity, dark circles are difficult to characterize and measure, with current assessment techniques relying on specialist equipment, image analysis or proprietary grading scales. There is therefore a need to develop and validate a photonumeric scale for assessing infraorbital dark circles, which can provide an objective and consumer relevant tool for evaluating this condition and the efficacy of treatment products and procedures.
- Methods : A panel of expert clinical evaluators reviewed approximately three thousand facial photographs collected over a 5-year period and selected images representing a dynamic range of dark circles. A 10-point photonumeric scale was created, with corresponding descriptors and images for each grade of the scale. To rigorously validate the scale, linearity, sensitivity and precision were assessed by colorimetry and in-clinic evaluation. Reproducibility was assessed photographically with both experienced and inexperienced clinical evaluators, whereas intragrader repeatability was assessed live in-clinic. The scale was then employed in a split-face randomized clinical trial on 58 subjects to evaluate the efficacy of a cosmetic treatment product over 8 weeks.
- Results : Colour analysis of the images showed the scale was linear, with statistically significant correlations observed when colour data (CIElab; Individual Typology Angle) were plotted against the corresponding grades (r > 0.9, P < 0.001). Colour difference (Delta E) was calculated between the infraorbital zone and the surrounding skin, and when data were plotted against the grades, a statistically significant correlation was observed (r = 0.99, P < 0.01). The magnitude of the Delta E suggested that changes in grade are visibly perceptible to the human eye, and therefore, the scale is sensitive and clinically relevant. Intergrader reproducibility showed strong correlation (0.96) and >90% agreement between experienced evaluators, whereas intragrader repeatability assessment showed >90% perfect agreement between grades. Use of this scale in a clinical trial demonstrated the efficacy of a cosmetic product, with a mean statistically significant (P < 0.001) decrease in grade of 0.74 compared to baseline, and 0.59 versus the untreated control, after 8 weeks of treatment.
- Conclusion : Our photonumeric scale for infraorbital dark circles is sensitive and robust and provides an objective and easy-to-use tool to evaluate dark circles and their treatment.Note de contenu : - MATERIALS AND METHODS : Creation of a photonumeric scale for infraorbital dark circles - Validation of the photonumeric scale - Clinical trial to evaluate the efficacy of a cosmetic treatment product

Tests d'efficacitéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : A UV-spectrophotometric method for the analysis of makeup remover was developed and validated according to ICH guidelines. Three makeup removers for which the main ingredients consisted of vegetable oil (A), mineral oil and silicone (B) and mineral oil and water (C) were sampled in this study. Ethanol was the optimal solvent because it did not interfere with the maximum absorbance of the liquid foundation at 250 nm. The linearity was determined over a range of makeup concentrations from 0.540 to 1.412 mg mL?1 (R2 = 0.9977). The accuracy of this method was determined by analysing low, intermediate and high concentrations of the liquid foundation and gave 78.59–91.57% recoveries with a relative standard deviation of <2% (0.56–1.45%). This result demonstrates the validity and reliability of this method. The reproducibilities were 97.32 ± 1.79, 88.34 ± 2.69 and 95.63 ± 2.94 for preparations A, B and C respectively, which are within the acceptable limits set forth by the ASEAN analytical validation guidelines, which ensure the precision of the method under the same operating conditions over a short time interval and the inter-assay precision within the laboratory. The proposed method is therefore a simple, rapid, accurate, precise and inexpensive technique for the routine analysis of makeup remover efficacy. Note de contenu : - Materials and instruments
